While attempting to replicate the navbar example from Bootstrap's documentation, I encountered an issue where the background color of the navbar was not loading properly.
<nav class="navbar navbar-inverse bg-inverse">
<a class="navbar-brand" href="#">Navbar</a>
</nav>
Upon checking bootstrap.css, I noticed that bg-inverse is not included there. Should I create the colors myself or am I making a mistake? (I am currently working on an Angular project)
